The Airstream is a simple box, available in silver or black. As you can see from the pictures, it is not the kind of design that will stand out on your AV rack.

Inside the Airstream is a slightly modified Apple Airport Express. This provides the wireless networking tools required to beam your music from a PC to the Airstream. From the Airport Express, the signal is then reclocked through some custom circuitry in order to eliminate jitter. Then it's on to the 24bit/192kHz DAC's provided by Cirrus Logic. The unit is powered by a high quality, low noise R-Core transformer.

One thing to note, even though the unit is capable of handling high resolution 24bit/192kHz files, the Airtunes protocol is still limited to 16bit/44.1kHz.
